Question on cascading LOV

Jose ArósteguiMar 16 2017 — edited Mar 17 2017

Hi experts,


I'm using Jdev 12.2.1.0 and I'm implementing 4 selectOneChoice with cascading dependencies.

It works fine by now as soon as you select values in order from 1 to 4, as the values are narrowed down:

But my problem is if users goes directly to value 4:

My requirement is that the list of field 4 is empty unless all previous 3 fields are not empty.

Thanks a lot,
Jose.
